Overview

The Sennheiser SL TS 133 GN Set DW-4 US is a wireless tablestand microphone for speech in boardrooms and lecture halls. It pairs an SL Tablestand 133-S DW with a MEG 14-40 B cardioid gooseneck microphone and an SL Rack Receiver DW, operating in the 1920-1930 MHz band. The BA 40 battery runs up to 10 hours, and the stand charges by Qi or USB. Suits Doha boardrooms and classrooms.

What the SL TS 133 GN Set DW-4 US includes

This set is a complete wireless speech pickup kit centred on a tablestand. The package contains the SL Tablestand 133-S DW, a MEG 14-40 B gooseneck microphone, a BA 40 rechargeable battery, an SL Rack Receiver DW with its power supply, a GA 4 rackmount kit, a quick guide and a safety guide. The manufacturer data lists everything needed for use and installation in the box, so a presenter can be set up without cables running across the table.

Frequency band and audio figures to check

This US variant, article number 506631, operates in the 1920-1930 MHz band. Confirm that the band suits your site and your other wireless equipment before ordering, because it is the first thing a radio planner will check. The microphone captures audio at 24 bit/48 kHz with a frequency response of 75 to 20,000 Hz, a dynamic range above 120 dB(A) and a signal-to-noise ratio above 90 dB(A). Total harmonic distortion is typically 0.1 %, and RF sensitivity is below -90 dBm.

Charging, battery life and remote control

BA 40 rechargeable battery rated at 3.6 V and 2.2 Ah, typically 10 hours of operation.
Dedicated battery status LEDs show remaining charge clearly.
Qi wireless charging or USB charging for the stand; the CHG 2W base for two mobile devices is sold separately.
Monitoring and control through the Sennheiser Control Cockpit.

Power consumption is rated at 350 mA. The gooseneck is 40 cm long, and the stand measures 405 by 350 by 73 (mm) and weighs 3,294.14 g in this variant, so plan the table space before ordering.

Where this set fits in Qatar

Three situations suit this configuration well:

A boardroom in West Bay or Msheireb: the chairperson speaks from a fixed tablestand position while the room system amplifies or records the voice, with no cables crossing the table.
A seminar room or lecture hall at a campus in Education City: the cardioid gooseneck is positioned toward a speaker at a lectern or seated panel, suiting lectures and panel discussions.
A government hearing room in Doha: an official reads from notes at a fixed table, while the system is run from a rack in a ventilated comms room.

Planning the installation

Three points decide whether this set works on your site. First, the rated operating temperature is 0 to 40 °C (14 to 131 °F). Summer temperatures in Qatar can exceed 45 °C, so keep the stand and rack receiver in air-conditioned spaces and check room temperature before installation. Second, confirm the 1920-1930 MHz band against the frequency plan for the room. Third, measure the table and the route from the rack so that the 40 cm gooseneck and cabling reach the speaker without strain.

SmartRooms Qatar offers free site surveys, delivery to all 8 municipalities of Qatar and professional installation. Government buyers can order against a purchase order or a Monaqasat tender, and the manufacturer warranty of 2 years applies. Send your room layout and the number of speaking positions to SmartRooms Qatar and request a quote; we usually respond within one working day.

Questions about SL TS 133 GN Set DW-4 US

Who is this tablestand microphone set designed for?

It suits organisations that need a wireless speech microphone placed on a table rather than a ceiling or floor system. The SL Tablestand 133-S DW with its MEG 14-40 B gooseneck is aimed at podium discussions, speeches and lectures. In Qatar that means a boardroom in West Bay, a seminar room in Education City or a government hearing room in Doha, where a single speaker needs clear pickup and no cables across the table.

Which radio frequency band does the DW-4 US use?

The DW-4 US variant, article number 506631, operates in the 1920-1930 MHz band according to its specifications. Before ordering, confirm that this band fits your site's frequency plan and any other wireless equipment in the room. The manufacturer data does not state licensing or local compliance in Qatar, so confirm that with the SmartRooms Qatar team. The stated RF sensitivity is below -90 dBm.

Will the gooseneck work with other Sennheiser microphones?

According to the manufacturer data, the stand is compatible with all Sennheiser XLR-3 gooseneck microphones. The set includes the MEG 14-40 B gooseneck with cardioid pickup, which is 40 cm long. If you later want a different gooseneck for a longer table or another speaking position, check its XLR-3 connector and mounting before buying, and ask SmartRooms Qatar to confirm the fit against your order.

How long does the battery last and how is it charged?

The BA 40 rechargeable battery, rated at 3.6 V and 2.2 Ah, gives typically 10 hours of operation. The stand can be charged wirelessly using the Qi standard or through USB, and dedicated battery status LEDs show remaining charge. The CHG 2W wireless charging base for two mobile devices is available separately and is not in the box, so include it in your quotation if you want it.

Can the set be used through a Qatari summer without overheating?

The rated operating temperature is 0 to 40 °C (14 to 131 °F), and that is the limit to plan around. Outdoor temperatures in Qatar can exceed 45 °C in summer, so use the set in air-conditioned meeting rooms and keep the rack receiver in a cooled, ventilated comms room. Do not place the stand near a sunlit window or a projector exhaust vent.

How much table space does the tablestand need?

The SL Tablestand 133-S DW measures 405 by 350 by 73 mm according to the manufacturer data, and the gooseneck adds 40 cm of reach. In a West Bay boardroom with a long table, place the stand at the speaker's seat and keep cable routing away from chairs. SmartRooms Qatar offers a free site survey to check the layout before installation.

Is it suitable for a lecture hall at a university campus?

It suits seminar rooms and smaller lecture halls with a seated or standing speaker behind a lectern. The cardioid pickup pattern and the 75 to 20,000 Hz frequency response suit direct speech. The manufacturer data does not state a coverage area, so for a large lecture theatre in Education City, ask SmartRooms Qatar to review the room before relying on a single microphone.

Can we monitor and control the set remotely?

Yes. The manufacturer states that the set can be monitored and controlled with the Sennheiser Control Cockpit. That lets an IT or AV team check the status of the wireless system from a central point rather than walking into the room. The data does not list network or software requirements, so confirm those with the SmartRooms Qatar team before ordering.

What comes in the box, and what do we connect to the audio output?

The box includes the SL Tablestand 133-S DW, the MEG 14-40 B gooseneck microphone, the BA 40 battery, the SL Rack Receiver DW with power supply, the GA 4 rackmount kit, a quick guide and a safety guide. The audio output is an XLR 3M connector. Plan an XLR cable from the set's audio output to your mixer or conferencing codec, and confirm its length with the installer during the site survey.

Can a government authority buy this through a tender?

Yes. SmartRooms Qatar supplies against purchase orders (LPOs) and government tenders, including Monaqasat, and accepts payment by bank transfer, cheque or purchase order. Quotations are usually issued within one working day. When you request a quote for a ministry hearing room, send the room plan and the tender reference so the quotation matches the specification you are assessing.

What warranty applies to this model?

The manufacturer data lists a 2-year warranty for this set, and SmartRooms Qatar products are covered by the manufacturer's warranty. Ask for the warranty terms in writing with your quotation so your procurement file records the exact conditions. Keep proof of purchase and the serial numbers of the rack receiver and tablestand for your records.

How does the cardioid gooseneck perform for speech pickup?

The MEG 14-40 B has cardioid directivity and is dedicated to speech, so it favours sound from the direction it faces. The set lists a signal-to-noise ratio above 90 dB(A), a dynamic range above 120 dB(A) and an input impedance of 30 kΩ. Position the gooseneck toward the speaker's mouth and test it in the room with the actual speakers before final commissioning.
